<p>PURPOSE:To make a device small-sized and lightweight by bringing down two covers, which are attached freely turnably to a cassette press-fitting plate, to the horizontal state when a cassette is inserted and ejected. CONSTITUTION:Covers 42 and 43 are moved back and forth in the vertical direction by a press-fitting plate 12, and a cassette insertion hole 32 is closed from the inside by the cover 42 before a cassette 34 is inserted, and the cassette insertion hole 32 is closed from the inside by the cover 43 when the cassette is set in a cassette set position. Consequently, when a holder 11 is moved back from the set position to the insertion position to eject the cassette 34, only a driving mechanism or moving back and forth of the holder 11 is enough, and the structure is simplified. Further, an anxiety of contacting of the cassette 34 with covers 42 and 43 at the ejection time is resolved, and the cassette 34 can be approximated to a front panel to improve a space factor. Especially, a space required for rise of covers 42 and 43 onto the holder 11 at the cassette insertion or ejection time is reduced, and the device is made small-sized and lightweight furthermore.</p> |
